2A Synchronous Buck Li-ion Charger




General Description



The LP28301 is a 5A Li-Ion battery charger intended for 4.4V~14V wall adapters. It utilizes a high efficiency synchronous buck converter topology to reduce power dissipation during charging. The LP28301 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V/4.3V /4.35V float voltage. When the adapter`s current capacity is less than the set charge current, the LP28301 would decrease the charge current automatically to keep the output of adapter would not be pull down by the chip. Additional features include shorted cell detection; temperature qualified charging and overvoltage protection. The LP28301 is available in a low profile QFN-28 package.
